Similarly, starting from isovialine, we successfully produced boldine with 6% yield and 62% e.e.

另外，利用异香草醛当起始物，经过十四步，可得到总产率6%、光学纯度62% e.e。

Miscellaneous compounds: Examples of this fourth group include vanillin, cinnamic acid,and geranyl formate.

其它化合物：第四类的例子有香草醛、肉桂酸和甲酸香叶酯。

objectiveto determine the content of the tritepenoidic acid in dracocephalum moldavica l .methodswith oleanolic acid as the standard,5% vanillin-acetic acid and perchloric as the developer,colorimetric method was applied.

目的测定香青兰全草中总三萜酸成分含量。方法以齐墩果酸为指标，采用香草醛-冰醋酸及高氯酸显色后用分光光度法测其含量。

Condition optimization for its efficient fermentation was also carried out. The reaction and separation system with the addition of resin HD-8 and the isoeugenol/aquoeus biphasic system of the biotransformation of isoeugenol to vanillin by Bacillus fusiformis CGMCC1347 were set up. The isolation and purification of isoeugenol and vanillin in both systems were studied. The reuse of the immobilized cells in biphasic system was successfully applied.

SW-B9的基础上，对该菌株进行了生理生化特性鉴定以及16S rDNA序列分析，命名为纺锤芽孢杆菌CGMCC1347；继而对该菌株的发酵条件进行了研究，首次建立了纺锤芽孢杆菌CGMCC1347转化异丁香酚生成香草醛的树脂分离耦合体系和异丁香酚—水两相体系，同时对此二体系的底物和产物的分离提取进行了研究，成功实现了两相体系中固定化细胞的反复利用。

Other compounds: such as Vanillin, Phenyl Acrylic acid and Geranyl Formate.

其它化合物：如香草醛、肉桂酸和甲酸香叶酯等。

Gymnemic acid can be determined by spectrophotometry of dealt with mixed liquid of 8% vanilin-sulphuric acid.

本文首先确定使用香草醛—浓硫酸比色法测匙羹藤酸含量。

Isoamyl acetate and vanillin were chosen as pure olfactory nerve stimulator. There were 2 types of tasks in the experiment.

两种任务，一个是单一醋酸异戊酯刺激，另一个在醋酸异戊酯前给予香草醛，以防止可能的嗅觉注意减低。

The biotransformations of isoeugenol to vanillin with various strains available in our lab were tested. It was found that several baterica including Bacillus subtilus 7658, Alcaligenes AS1.7617, Brevibacterium flavum 1.7a and Brevibacterium flavum AS1.013 could convert isoeugenol to vanillin.

对实验室所保藏的细菌、放线菌、真菌进行初步筛选发现细菌中枯草芽孢杆菌7658、粪产碱杆菌AS1.7617、黄色短杆菌1.7a、黄色短杆菌AS1.013能产生少量香草醛，最高浓度为0.31 g/L；放线菌中诺卡氏菌Nocardia sp。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
